Description

The present invention relates to a folding bicycle that can be folded and made to stand on its own by an easy operation, and a bicycle cover that is used by covering the bicycle when the bicycle is folded and transported.

First, the prior art regarding a folding bicycle will be described. The following Patent Documents 1 and 2 are documents relating to the prior art of folding bicycles.

Bicycles have traditionally been used as an easy means of transportation, and in recent years, various folding bicycles have been provided for carrying while using public transportation such as trains, or for mounting in automobiles. There is. There are various types of folding bicycles according to the purpose of use, such as those that are compact and suitable for transportation in the folded state.

As one of the purposes of using such folding bicycles, in recent years, there is an increasing need for a means of transportation in combination with public transportation, such as carrying a bicycle and using a train. Folding bicycles used in such means of transportation are required to have various functions such as miniaturization of the vehicle body, compactness in the folded state, ease of transportation, etc., assuming that the user transports the vehicle body. Will be done. In addition, when the folding bike is run after using public transportation other than when the folding bike is being transported, the vehicle body is stable regardless of the environment regarding the mutual deformation operation of the traveling form and the carrying form (folded state). It is hoped that it can be done in the same state.

The folding bicycle of Patent Document 1 is provided in consideration of the deformation operation to the carrying form and the ease of transportation. In the folding bicycle of Patent Document 1, the substantially center of the main frame and the handle pipe open and close at the same time, and the folding bicycle is transformed from a traveling form to a carrying form. In addition, a carry is provided on the loading platform so that the folding bicycle can be transported stably.

The folding bicycle of Patent Document 2 has a structure in which the entire vehicle body is in an upright state by grounding the loading platform provided at the rear of the folding bicycle when the bicycle is transformed from the traveling form to the carrying form, and then the main frame is substantially folded and folded. ing.

Subsequently, the prior art regarding the bicycle cover will be described. The following Patent Documents 3 to 6 are documents relating to the prior art of a bicycle cover.

When a bicycle occupant carries a bicycle by public transportation (railway, ship, airplane, etc.), it is called rinko. It is often obligatory to put the bicycle in a bag during such a round trip.

It is common practice to cover a folding bike and carry it with you, even when you are not traveling around.

Japanese Unexamined Patent Publication No. 2012-176638 Japanese Unexamined Patent Publication No. 2010-184523 Japanese Unexamined Patent Publication No. 2010-17199 Japanese Unexamined Patent Publication No. 2008-44486 Registered Utility Model Gazette No. 3034644 Registered Utility Model Gazette No. 3013400

However, in the folding bicycle of Patent Document 1, when the folding work is performed, the substantially center of the main frame and the connection portion with the head pipe are bent at the same time. Therefore, not only the posture of the main frame changes in the folding work, but also the saddle attached to the rear wheel side of the main frame also tilts rearward, and the posture of the entire vehicle body changes greatly. When the vehicle body is in an unstable posture in this way, it is necessary for the user to support and stabilize the vehicle body while transforming it into a carrying form. In some cases, the vehicle body may be in an unstable posture and may fall. Therefore, it is necessary to consider the place where the folding bicycle is deformed and avoid the place where many people come and go.

Further, in the folding bicycle of Patent Document 2, it is necessary to lift the front wheel side upward and stand it substantially vertically over the entire length of the vehicle body in order to carry it. Although the folding bicycle can be deformed in a small space, such an unstable posture of the vehicle body further increases the risk of the vehicle body tipping over.

As described above, in the prior art, the structure is not such that the vehicle body is stabilized in the folding operation. Although various folding bicycles that have been made lighter are provided, there is a limit to the weight reduction due to the structure of the bicycle, and it is desirable that the folding bicycle does not require the action of lifting the folding bicycle for transformation to a carrying form. ..

Therefore, it is an object of the folding bicycle of the present invention to realize the deformation operation in a stable state without significantly changing the posture of the vehicle body with respect to the mutual deformation of the traveling form and the carrying form.

A general-purpose wheel bag is a bag whose overall shape is made of cloth or the like, and has an opening that is large enough to accommodate a folded bicycle and a means for opening and closing a fastener or the like provided on the periphery of the opening. , And a belt for carrying around on the shoulder.

Such a conventional bicycle bag has a drawback that it must be laid on the ground when accommodating a folding bicycle, and the bicycle bag becomes dirty at that time. On the other hand, with a bicycle bag that can be placed over the bicycle, there is little risk that it will get dirty when the bicycle is stored, but since the bicycle body and the bicycle bag are separate, there is a risk that you will forget to carry the bicycle bag. There is. If you bring it to a public institution, forgetting it is a fatal defect and there is a concern that you will be denied boarding the public institution.

In addition, when accommodating a folding bicycle in a bicycle bag, the bicycle must be laid on the ground and the bicycle must be carried to the position where the bicycle bag is laid, which is troublesome to accommodate.

Furthermore, when the bicycle bag containing the folding bicycle is hung on the shoulder using a belt or carried by hand, the weight of the folding bicycle shall be applied to the belt and the bicycle bag to which the belt is attached. become.

In this way, the weight of the bicycle is supported by the wheel bag, and it is necessary to use a material with high strength for the wheel bag. In other words, the wheel bag is required to use a thick and sturdy material, and the wheel bag itself is inevitably heavy and bulky.

Further, in the cover of the present invention, the cover main body can be taken in and out from the opening of the first accommodating portion while the first accommodating portion is attached to the rod-shaped portion of the object to be covered. Therefore, the cover main body can be taken out from the first accommodating portion with the first accommodating portion attached to the rod-shaped portion of the covering object to cover the covering object. As described above, the cover of the present invention can be attached to the rod-shaped portion of the object to be covered through the case where the object to be covered is covered and the case where the cover is not covered. As a result, the cover of the present invention can prevent the cover from being forgotten to be carried, and can quickly cover the object to be covered when it is desired to cover the object to be covered.

In the cover of the present invention, the object to be covered is a bicycle having a rod-shaped portion, and the cover main body has an introduction portion capable of forming an opening through which a part or all of the bicycle can be taken in and out, and the first accommodating portion. It has a connection portion connected to the cover body, and can be accommodated in the first accommodating portion through any one of the openings provided in the first accommodating portion by rolling a part or the whole of the cover main body. It is characterized by being.

When the cover of the present invention is intended to cover a bicycle, the cover body can be taken out from the first accommodating portion and the bicycle can be covered through the opening of the introduction portion. Further, when the cover of the present invention does not cover the bicycle, the cover body can be rolled up and accommodated in the first accommodating portion through the opening of the accommodating portion. Further, in the cover of the present invention, the cover can be attached to the rod-shaped portion (pipe portion or the like) of the bicycle depending on whether the bicycle is covered or not. As a result, the cover of the present invention can prevent the cover from being forgotten to be carried, and can quickly cover the entire or part of the bicycle in response to sudden rain or the like.

Here, a bicycle including a folding bicycle is generally configured to have wheels, a main frame, a front wheel frame, a rear wheel frame, a saddle, a front basket, and the like. When covering all of these bicycle configurations (entire bicycle), it is necessary to cover the saddle, front basket, etc. that protrude away from the main frame. Therefore, when the entire bicycle is to be covered with one bag, it is necessary to make the bag (main body cover) an appropriate size.

However, there are cases where the main parts such as wheels and main frames and the parts such as saddles and front baskets are in different situations to be covered. For example, if the bicycle to be covered by the cover is a folding bike, it may be attempted to cover the bicycle in order to carry the folding bike and board public transportation (transportation). When the cover is used for the purpose of transporting such a folding bicycle, it may be sufficient to cover only the main part including the wheel and main frame of the bicycle, and it may not be necessary to cover the saddle or the front basket.

On the other hand, when riding a bicycle wet with rain, the user may want to cover only the saddle or the front basket. In such a case, it is difficult to use a cover having only a cover body that covers the entire bicycle depending on the situation. Furthermore, the saddle, front basket, etc. are often configured to protrude from the main part of the entire bicycle, and if the entire bicycle including both the saddle and the main part of the bicycle is covered, it is useless in the cover body. A large storage area will be created, and the appearance of the bicycle and the entire bag will have to be increased.

It has a possible sub-cover body, the sub-cover body is connected to the first accommodating portion, and the sub-cover body can be accommodated through an opening formed in the first accommodating portion. It is characterized by.

According to the above configuration, when the bicycle is to be covered, the main part of the bicycle can be covered with the cover main body, and the parts such as the saddle and the front basket can be covered with the sub-cover body. That is, if the main part of the entire bicycle is covered with the cover body and the saddle or the like is covered with the sub-cover body, the covered state is compared with the case where the entire bicycle is covered with one bag body. Bicycles and bicycle covers can be made compact. As a result, the cover body can be made compact by using the cover body as a bag body having a relatively small storage area. Further, the bicycle, which is the object to be covered, can be covered depending on the situation in which the object to be covered is to be covered and the part to be covered.

The cover of the present invention has a second accommodating portion in which the object to be covered is a part or all of a bicycle having a rod-shaped portion and can accommodate the sub-cover body, and an opening is provided in the second accommodating portion.

Part or all of the above may be accommodated in the second accommodating portion.

According to the above configuration, with the auxiliary cover body housed in the second storage part, only the cover body can be taken out from the first storage part to cover the main part of the bicycle. On the other hand, when the saddle or the like is to be covered by the auxiliary cover body, the auxiliary cover body can be expanded to cover the saddle or the like while the cover main body is accommodated in the first accommodating portion. That is, while accommodating each of the cover main body and the sub-cover body, the target portion of the bicycle can be covered depending on the situation in which the main part of the bicycle, the saddle, or the like is to be covered. As a result, according to the cover of the present invention, the cover can be used in various modes depending on the situation, and the convenience of the user is improved.

The cover of the present invention may have a part or all of the openings that can reduce the size of the opening area.

If the opening area of the cover main body or the sub-cover body can be narrowed down, the state of covering the object to be covered can be maintained more reliably. That is, the cover of the present invention can prevent the cover main body and the sub-cover body from being blown by the wind and coming off from the object to be covered. Further, if the opening area of the first accommodating portion and the second accommodating portion can be narrowed down, the state in which the cover main body and the sub-cover body are accommodated can be more reliably maintained.

The cover of the present invention may have a part or all of the openings made shrinkable by an elastic member having elasticity.

If the openings of the cover body and the sub-cover body can be expanded and contracted, the state of covering the object to be covered can be maintained more reliably. That is, the cover of the present invention can prevent the cover main body and the sub-cover body from being blown by the wind and coming off from the object to be covered. Further, if the openings of the first accommodating portion and the second accommodating portion can be expanded and contracted, the state in which the cover main body and the sub-cover body are accommodated can be more reliably maintained.

In the traveling mode of the folding bicycle 10, the stand portion 70 is prohibited from swinging backward and is positioned at a position where the bottom surface of the positioning portion 132 and the top surface of the positioning base 134 are in contact with each other. Further, by positioning the end portion of the second lock member 136 in the direction of the positioning portion 132, the positions of the positioning portion 132 and the positioning base 134 are locked. As a result, the folding bicycle 10 maintains its traveling mode.

As shown in FIG. 7, the stand form holding mechanism 140 includes a locking portion 142 provided on the main frame 20 side and a locked portion 144 provided on the stand portion side. The locking portion 142 is provided with a protrusion 143. Further, the locked portion 144 is provided with a locking hole 145. As shown in FIG. 7A, the locked portion 142 and the locked portion 144 are in a released state in the traveling mode. On the other hand, as shown in FIG. 7B, in the stand form of the folding bicycle 10, the protrusion 143 is fitted into the locking hole 145, and the locking portion 142 and the locked portion 144 are locked. As a result, the folding bicycle 10 can maintain the stand form.

Next, the configuration of the handle portion 150 will be specifically described. FIG. 8 is a perspective view of the handle portion 150. The handle portion 150 includes a mounting portion 156 that is attached to the seatpost 27, and a protruding portion 152 that projects substantially horizontally from the mounting portion 156.

The protrusion 152 is formed by bending a bar, and both ends of the bar are welded and fixed to the mounting portion 156. The protruding portion 152 has a shape that protrudes substantially horizontally from the mounting portion 156 in a state of being mounted on the seatpost 27, and a grip portion 154 that is bent upward is formed at the end portion on the protruding side.

A third lock member 158 is attached to the attachment portion 156, and when the attachment portion 156 is locked by the third lock member 158, the attachment portion 156 is fixed in the attachment position and attachment direction. When the lock of the third lock member 158 is released, the mounting position and mounting direction of the mounting portion 156 can be changed. As a result, the handle portion 150 can rotate in the circumferential direction with respect to the seatpost 27, and can also move in the axial direction.

In the traveling mode of the folding bicycle 10, when the grip portion 154 is arranged in a posture facing the rear of the vehicle body, baggage or the like can be hooked on the handle portion 150 and used as a luggage hanging portion. Further, as shown in FIG. 10, in the carrying mode of the folding bicycle 10, the direction of the grip portion 154 can be selected according to the convenience of the user.

Subsequently, the transformation of the folding bicycle 10 from the traveling form to the stand form and further from the stand form to the carrying form will be specifically described with reference to the drawings.

As described above, in the folding bicycle 10, the stand portion 70 is integrally swingable. As shown in FIG. 2, when the stand portion 70 is rotated in a direction approaching the front wheel 42 and rotated to a position where the carries 110a and 110b touch the ground, the folding bicycle 10 forms a stand form. Although not shown in FIG. 2, the locking portion 142 and the locked portion 144 of the stand form holding mechanism 140 are in a locked state. Further, in the stand form, the carry 110a and 110b, the rear wheel 74 and the front wheel 42 are in a stable state by being grounded at four points. In the stand form, the folding bicycle 10 is in a state of being reduced in the longitudinal direction.

In the stand form of the folding bicycle 10, the center of gravity of the stand portion 70 is located in the region extending from the ground contact point of the carries 110a and 110b to the ground contact point of the rear wheel 74 in the longitudinal direction. Therefore, the folding bicycle 10 can stably stand on its own in the stand form.

Subsequently, the operation when the user transforms the folding bicycle 10 from the traveling form to the stand form will be described with reference to the drawings. FIG. 9 shows the middle of the operation in which the user transforms the folding bicycle 10 from the traveling form to the stand form. As shown in FIG. 9, while holding and supporting the handle 49, the user hooks his toes on the first horizontal rod 105 (rear end side horizontal rod) and presses the first horizontal rod 105 downward with his foot to press the stand portion. Swing 70. In the deformation operation of the folding bicycle 10 to the stand form, the rear wheel 74 rotates while being in contact with the ground, and the stand portion 70 integrally swings in a direction approaching the front wheel 42. When the stand portion 70 swings to a position where the carries 110a and 110b touch the ground, the stand form is formed. In the stand form, the carries 110a and 110b are located below the seat tube 26.

Further, the stand portion 70 is configured to rotate around an axis (axis center of the rotating portion 60) extending in a direction along the axle of the rear wheel 74. Therefore, the stand portion 70 and the rear wheel 74 rotate in the same direction. Therefore, the entire stand portion 70 can be stably rotated forward of the vehicle body while the rear wheel 74 is grounded and rotated.

In this way, the user does not need to lift the folding bicycle 10 when transforming the folding bicycle 10 into the stand form, and the folding bicycle 10 can be transformed into the stand form by the same operation as operating the stand in a normal bicycle. It can be carried out. As a result, the folding bicycle 10 can be easily transformed into a stand form in which the vehicle body is erected and the longitudinal direction is reduced.

Next, the carrying form of the folding bicycle 10 will be described. FIG. 3 is a side view of the folding bicycle 10 in a carrying form. In the carrying mode of the folding bicycle 10, the lock of the first joint portion 30 is released from the above-mentioned stand form to fold the main frame 20, and the lock of the second joint portion 50 is released to lower the handle post 48 and the handle 49. It is in a folded state. As shown in FIG. 3, in the carrying mode, the folding bicycle 10 is folded in the longitudinal direction reduced to substantially the same length as the main frame 20.

As described above, the folding bicycle 10 in the carrying form is suitable for the user to carry the folding bicycle 10. Further, in the folding work of transforming the folding bicycle 10 into a carrying form, the user can first make the folding bicycle 10 into a stand form. Therefore, the total length of the body of the folding bicycle 10 can be reduced, and the folding bicycle 10 can be made to stand on its own by the carry 110a, 110b, the rear wheel 74, and the like (stand form), and can be further transformed into a carrying form.

Subsequently, a case where the user carries the folding bicycle 10 in the carrying form will be described. FIGS. 10 (a) and 10 (b) show a state in which a user carries a folding bicycle 10 in a carrying form while towing it.

In FIG. 10A, the protruding portion 152 of the handle portion 150 is arranged so as to face the rear side in the traction direction of the user from the seatpost 27. As shown in FIG. 10A, when the user grips the handle portion 150, the entire body of the folding bicycle 10 is tilted. In this state, the pair of carries 110a and 110b are in contact with the ground, and the front wheels 42 and the rear wheels 74 are not in contact with the ground. Further, in the operation of towing and transporting the folding bicycle 10, the center of gravity of the folding bicycle 10 (reference numeral G in the figure) is located in the region between the carries 110a and 110b and the user. Further, the carry 110a and 110b rotate in a direction intersecting the axes of the carry 110a and 110b arranged substantially in parallel, and the folding bicycle 10 can be stably towed and carried.

Further, as shown in FIG. 10B, it is also possible to arrange the protruding portion 152 from the seatpost 27 toward the front in the towing direction of the user, and tow and carry the folding bicycle 10. In this case, the body of the folding bicycle 10 which is to be carried can be towed and transported in the horizontal direction while being self-supporting without tilting the vehicle body.

As described above, the folding bicycle 10 can select the direction and the position of the protrusion 152 according to the convenience when the user carries the folding bicycle 10.

Subsequently, a case of holding the vehicle body position of the folding bicycle 10 will be described with reference to the drawings. FIG. 11 shows a case where the user holds the vehicle body position while stepping on the first horizontal rod 105 (rear end side horizontal rod) of the folding bicycle 10 which is a carrying form. In FIG. 11, the front wheel frame 40 and the saddle 28 are not shown.

As described above, in the folding bicycle 10, the first horizontal rod 105 and the rotation axes of the carries 110a and 110b are located close to each other. As shown in FIG. 11, in the carrying mode of the folding bicycle 10, the first horizontal rod 105 is located close to the ground. When the user steps in the direction of pushing down the first horizontal rod 105 with his / her foot, the carries 110a and 110b are pressed downward with the heel touching the ground, and the carry 110a and 110b are in a braked state. As a result, the vehicle body position can be maintained so that the vehicle body of the folding bicycle 10 does not move.

≪When equipped with a three-wheeled carry≫
Subsequently, a modified example in which the carry 110a, 110b (wheels) of the folding bicycle 10 is changed to the three-wheel carry 210a, 210b will be described. As shown in FIG. 12A, the three-wheel carry 210a, 210b includes a connecting portion 218 having three auxiliary wheels 214a, 214b, 214c and a wheel support portion extending radially in three directions around the central shaft 212.

The auxiliary wheels 214a, 214b, and 214c are rotatably attached to the connecting portion 218 with the wheel shafts 216a, 216b, and 216c as the rotation centers, respectively. The connecting portion 218 is rotatably attached to the loading platform portion 100 with the central axis 212 located at the center of the substantially equilateral triangle S as the center of rotation.

FIG. 12B shows a traveling mode of a folding bicycle 200 equipped with a pair of three-wheeled carries 210a and 210b. As shown in FIG. 12B, the three-wheel carries 210a and 210b are attached to the rear end of the vehicle body of the loading platform 100 in the folding bicycle 200.

FIG. 13 shows the movements of the three-wheeled carries 210a and 210b when the folding bicycle 200 in the carrying form is carried on a step such as stairs. In FIGS. 13 (a), 13 (b) and 13 (c), the folding bicycle 200 is towed in a direction toward the upper side of the step (“traction direction” in FIG. 13). In FIG. 13, only the three-wheeled carries 210a and 210b are shown, and the other configurations of the folding bicycle 200 are not shown.

FIG. 13A shows a state in which the auxiliary wheels 214c are in contact with the side surface of the step while the two auxiliary wheels 214b and 214c are in contact with the ground. In this state, when a force is applied to the three-wheel carries 210a and 210b in the traveling direction, the three-wheel carry 210a and 210b rotate around the wheel shaft 216c as the center of rotation. When the three-wheel carries 210a and 210b rotate around the wheel shaft 216c, the auxiliary wheels 214a come into contact with the top surface of the step as shown in FIG. 13B. When the three-wheel carry 210a, 210b is further pulled in the towing direction from the state where the auxiliary wheel 214a is in contact with the top surface of the step, the three-wheel carry 210a, 210b rotates around the wheel shaft 216a. Then, as shown in FIG. 13 (c), when the auxiliary wheel 214c is towed upward along the side surface of the step and is towed in the horizontal direction as it is, the step can be climbed as shown in FIG. 13 (d).

As described above, by adopting the three-wheeled carry 210a and 210b, the user can smoothly carry the folding bicycle 200 on the stairs. As described above, by using the three-wheeled carry 210a and 210b, the folding bicycle 200 can be relatively easily transported on a step such as a staircase.
